ASHLAND, Ore., Aug. 12, 2014 /PRNewswire/ -- Two recently published scientific studies add to a growing body of research on the ecological importance of forest fires, even severe ones, in the western U.S, particularly California's Sierra region. Photo - http://photos.prnewswire.com/prnh/20140811/135259 One study, published in Natural Areas Journal (http://www.bioone.org/doi/abs/10.3375/043.034.0317), documented the ecological importance of forest fires for numerous plants and...

Carbon Capture Increased From Predation On Invertebrates By Woodland Salamanders
2014-03-11 09:17:59

USDA Forest Service - Pacific Southwest Research Station Woodland salamanders perform a vital ecological service in American forests by helping to mitigate the impacts of global warming. Global warming occurs when greenhouse gases like carbon dioxide are released into the atmosphere. Woodland salamanders facilitate the capture of this carbon before it is released by feeding on invertebrates (beetles, earthworms, snails, ants, etc.) that would otherwise release carbon through...

redOrbit Staff & Wire Reports - Your Universe Online By studying thousands of canopy tree species in the western Amazon, researchers from the Carnegie Institution for Science’s Department of Global Ecology have uncovered geographically nested patterns of chemical traits they say will help determine how the ecosystem will respond to changes in land use and climate. Writing in the March 3 edition of the Proceedings of the National Academy of Sciences (PNAS), the study authors set...

Forest Model Predicts How Trees Compete For Canopy Space
2014-02-20 11:53:17

Brown University Out of an effort to account for what seemed in airborne images to be unusually large tree growth in a Hawaiian forest, scientists at Brown University and the Carnegie Institution for Science have developed a new mathematical model that predicts how trees compete for space in the canopy. What their model revealed for this particular forest of hardy native Metrosideros polymorpha trees on the windward slope of Manua Kea, is that an incumbent tree limb greening up a given...

As trees grow larger in even-aged stands, competition develops among them. Competition weakens trees, as they contend for soil moisture, nutrients, and sunlight. Competition also increases trees’ risk to bark beetles and diseases, and subsequently leads to a buildup of dead fuels. A recent study, led by Dr. Jianwei Zhang, research forester at the U.S. Forest Service’s Pacific Southwest Research Station, considered if the onset of this risk could be determined. The study, which appears in...

A team of scientists from the USDA Forest Service's Pacific Southwest Research Station and the University of Córdoba in Spain recently developed a new methodology that measures the economic impact of forest fires on timber resources. When evaluating and planning fire management program activities, it is important to know the value of the forest ecosystems protected. However, determining the true volume or economic value of the resources lost during a fire can be difficult. For...

The number of sugar maples in Upper Great Lakes forests is likely to decline in coming decades, according to University of Michigan ecologists and their colleagues, due to a previously unrecognized threat from a familiar enemy: acid rain. Over the past four decades, sugar maple abundance has declined in some regions of the northeastern United States and southeastern Canada, due largely to acidification of calcium-poor granitic soils in response to acid rain. Sugar maple forests in the...

New Effect Of Acid Rain On Forests
2011-12-09 03:49:42

Too Many Dead Leaves a Bad Sign for Sugar Maples Scientists have discovered that nitrogen that falls from the atmosphere in acid rain can influence large tracts of sugar maples in North America. The atmospheric nitrogen in acid rain can affect forest ecosystems by acidifying soils and causing nutrient imbalances. Sugar maples in northeastern North America are especially vulnerable. Vast maple areas have been affected by this acidification process, which depletes soil calcium in...

Forest Gardening
2013-07-31 15:46:47

Forest gardening is a woodland ecosystem that requires little maintenance. Forest gardening is a form of intercropping that is a seven tier, layering system utilizing the space from the sub-ground up to the canopy in order to provide high yielding food production for human consumption in wooded areas. Layering utilizes the photosynthesis to the maximum benefit for each tier within the forest garden. The canopy level consists of the tallest fruit/nut trees with dwarf trees in the...

Rainforests
2013-04-19 19:33:20

Rainforests are forests that are characterized by high levels of rainfall, with definitions based on a minimum usual annual rainfall of about 68 to 78 inches. The monsoon trough, or otherwise known as the intertropical convergence zone, holds an important role in producing the climatic conditions that are essential for the Earth’s tropical rainforests. About 40 to 75 percent of all biotic species are native to the rainforests. It’s been estimated that there might be many millions of...
